Improving Pollination Efficiency, Yield and Fruit Quality of Two Date Palm Cultivars using Growth Activator

Date Palm Pollen: Features, Production, Extraction and Pollination Methods

“…Table 2 summarizes the efficiency of different pollination methods evaluated in various countries, where the efficiency of each method was evaluated through its FSP. Studies carried out in Egypt evaluated the traditional pollination method (strands placement) against water suspension and hand pollen dusting, concluding that DPP in water suspension and hand pollen dusting were the most effective methods [84][85][86]. In the first study, the traditional method had the highest FSP due to the excessive number of strands in the bunch, and an activation material (boric and ascorbic acids, treacle, and vinasse) resulted in a higher FSP [84].…”

“…This work also evaluated the stimulation and acceleration of pollen germination using a solution of 12% sucrose, 0.1 g K 2 SO 4 , 0.2 g MgCl 2 , 0.3 g Ca(NO 3 ) 2 , 0.1 g H 3 BO 3 , 200 mg/L vitamin B1, 50 mL/L Vitamin B6, and 1.0 mg/L Vitamin B12 prior to pollination; treatments receiving this treatment had the highest FSP. The third study added to its hand dusting treatments a natural growth activator called "Milagro", which is extracted from flower pollen; this addition improved the FSP [86]. In investigations in Saudi Arabia, the hand spraying of a pollen suspension proved to be the most effective; however, due to ease of operation and cost reduction, the use of a motorized pollinator was recommended [67,70,87].…”
